description
Description. The male and female of this species were redescribed by Ledoux (2004), but the internal structure of the female genitalia was not described. As female specimens were found among the specimens studied and the internal structure of the genitalia is provided here. Epigynum (Figs 73 – 74): longer than wide, with a pentagonal central depression; copulatory openings in the antero-lateral edge of the depression; internally copulatory ducts proceed anteriorly, curving posteriorly in four loops before ending anteriorly in the long sausageshaped spermathecae; fertilization ducts exit spermathecae posteromedially.
diagnosis
Diagnosis. C. insulare is similar to C. halophilum Schmidt & Piepho, 1994 from Cape Verde, but females can be differentiated by the shape of the central depression of the epigynum (pentagonal versus transversely oval, respectively) and the internal structure of the genitalia (compare Figs 73 – 74 and figs 47 – 48 in Lotz 2007 a), and males by the thin curved TA (see Lotz 2007 a: figs 55 – 56).
distribution
Distribution. Known from Réunion now recorded from Madagascar for the first time here, from a single locality (Fig. 53). Habitat. The type specimens were collected from a cave (Vinson 1863), and the other specimens from Réunion were collected by beating foliage and from a tree canopy (Ledoux 2004). The Madagascan specimens were collected in spiny forest / thicket.
